SHADE ROLLER.

Application ledNovember 13, 1924.v Serial No. 749,611.

To all whom t may concern Be it known that I, VALDEMAR JOHANsEN, acitizen of Denmark, and resident of Brooklyn, in the county'of Kings andState of New York, have invented certain new and useful Improvements inShade Rollers, of which the following is a specification.

This invention relates to shade rollers. The object of the invention isto provide a shade roller having a plurality of individual shadesarranged to be operated at an angle to the longitudinal axis of theshade roller. The advantageof such a shade rolleris that the shades maybe let down and operated to shade whatever objects are to be protected,and at the same time, the shade strips may be turned to permit theobjects to be seen through the open spaces between the shade strips. Theinvention may alsobe embodied in stage curtain or side wings.

With the above objects in view, my inven tion is embodied in a shaderoller constructed and arranged as hereinafter set forth and isillustrated in the accompanying drawing in which- Fig. 1 is a view of ashade roller embody ing my invention with parts in section and partsbroken away.

Fig. 2 is a sectional view on line 2-2 of Figure 1.4

Fig. 3 is a diagrammatic top plan view illustrating the principle of theinvention.

Referring to the drawing the reference numeral 4 denotes a tube orhollow roller of required length. The roller is preferably made of verythin or light material such as tin, aluminum or the like.

Into each end of the tube 4 there is tted a head 5 having a shaft orstud 6 whereby the shade roller is journaled in suitable bearings 7, 8suitably attached to the frames 9 of a window or opening.

As seen in Figure 2, the tube 4 does not form a complete or perfectcylinder. The bottom portion of the tube is bent inward to form flanges10, 10 to which is secured a base plate 11 which extends throughout thelength of the tube.

The shade roller may have as many shade strips as may be desired. I haveillustrated a shade roller carrying three shades 12, 13 and .14 by wayof example.

Each shade strip is provided with a top member or rod 15 and a bottomweight member 16. Each shade strip is suspended from a hanger 17 pivotedin the base plate 11 and which carries avpinion 18 withinthe tube.Inside the latter there `is located a shade operating shaft 19 journaledin suit able bearings 20, 20. The shaft 19 carries bevel gears 21 whichmesh with the pinions 18.

The shaft 19 is operated by means of a bevel gear 22 which meshes with apinion 23. The shaft 24 of the latter carries a clutch member 25 adaptedtoV be coupled to a clutch member 26 onda shaft 27. The latter issupported in the shade bracket 7 and below the bracket there is provideda universal joint 28 to which 'an actuating shaft or rod 29`is secured.The clutch members 25 26 are kept in engagement by a spring 30 whichbears against a collar or flange 31 on the shaft 27. A sleeve 32 maysurround the spring to prevent it from dirt and dam* age.

Suitably spaced on the shade roller and between each shade strip thereare secured to the roller suitable guiding flanges 33, 33. At one endthe shade roller carries a sprocket wheel 34 operable by a chain 35.

As seen in Figure 1, the shades are unrolled and hang straight down fromthe roller. If it is now desired to turn the shade strip at an anglesuch for instance as is illustrated in Figure 3, the operator takes holdof the rod 29 and turns the same, thereby rotating the pinion 23, henceturns the gear 22 and the shaft 19. Thus all the gears 21 are rotated,which in turn rotate the pin* ions 18 and hangers 17 to adjust theshades to the desired angle. Before rolling the shades up, they areagain turned back to parallel position with the roller axis.

The shades may then be rolled up by rotating the tube 4 throughoperation of the chain 35 and sprocket wheel 34 as is obvious. A reversemovement unrolls the shades.

rIhe shades are guided during the unrolling and rolling up operations bythe flanges 33. The length to which the shades are unrolled isdetermined by and adjusted by the operation of the chain 35.

While the shades are being unrolled or rolled up, the clutch 25-*26 mustof course be unclutched, and this may be done by pulling down the rod 29against the force of the spring 30, until a stop 40 on said rod isbrought below and set against a bracket 41 aflixed to the wall. Thebracket 41 is forked to permitjthe rody to be disengaged therefrom. Whenthe shades arey unrolled, the stop 40 is moved out from under thebracket 41:1. and; the Spring .30 vther ,automatically clutchestheshafts 27 and 2i together. Y Y

The universal joint 28 is desirable because it permits the operator tostand awaj"v 'from the shade roller while operating it.k

It will be seen that my' inventi'onprovides' a shade roller comprising aplurality of individual shade strips' which may be unrolled and againrolled up like an ordinary shade or roller curtain; j

In addition the sha'defs'tri-ps may be adjiisted` in parallel rinangular relation to the a'xisy of the shade roller, sons to provideth'erequired shade, yet permit objects behind thelshfa'de t0 be seen. j y jWhile I have disolosed `my invention in its preferred form,nevertheless, I do not desire tobe limited to ythe yexact details shown,as changesvor modiications may readilygbe made in the detailedconstruction without departing from the principle of th'ev invention orthe scope of the appended claims.

I claim:r-- j j i j l; The Combinationofsup rting brackets, a hollowroller mounted therein anplu-y rality of shades pivoted tosaid roller,means within the roller for adjusting said shades in angular lrelationto the roller, operating in, a lplurality of shades pivoted to saidroller, gearing mechanism within the roller for moving said shades intoangular rela# tion with' said roller,I mechanisml for actuating saidgearingI nielitnifsni at will and a sprocketand chainy for operating"said roller to lraise and lofwe'r the said shades;

3; The' eombinat'ionv of supporting means, a hollow ,roller mounted torotate therein, al of shade'sfpiivotaflly connected to said roller,gearing mechanism within the roller for rotating said'sliade's on' theirpivotal connections,pfmeans for rotating said roller .to raise and lowerthe said shades and a device adapted 'to bejc'lntched tsaid gear ingmechanism to operate the latter after the 'shades have been lowered andyadapted to be uncliitched from vsaid gearing mechanism preparatory toth'e raising of the said shades.
